CONDUCTIVE BALL WITH NANO METAL PARTICLES BONDED TO POLYMER BEAD AND PREPARATION METHOD THEREOF

摘要

The invention and the metal layer through the chemical bonding of the polymer to induce the strong bonding force between the metal and the polymer surface cracks and prevent segregation of the metal layer, preventing the conductivity decreased due to cracking of the metal layer to provide a surface conductivity is improved and a method of manufacturing a conductive ball. The method of producing a conductive ball according to the present invention, the first step of the polymer bead surface modified ionization; A second step of adsorption to the ion-modified polymer beads; A third step of reducing the adsorbed ions; And it comprises a fourth step of forming a metal layer by ionic bonding to the reduced ionic. A conductive ball according to the present invention has a laminated structure in the form of nanoparticles, the metal layer is not a continuous film shape formed on the surface, but this delamination phenomenon of the metal layer not, represents a stable resistance characteristics.
